Details

In the Linux kernel, the following vulnerability has been resolved:

drm/i915/gem: Fix NULL deref in I915_CONTEXT_PARAM_SSEU

Setting context engine slot N into I915_ENGINE_CLASS_INVALID / I915_ENGINE_CLASS_INVALID_NONE and attempting to apply I915_CONTEXT_PARAM_SSEU to the same slot N will deref NULL. Fix that.

Discovered using AI-assisted static analysis confirmed by Intel Product Security.
